FAST PATH PACKET DESTINATION MECHANISM FOR NETWORK MOBILITY VIA SECURE PKI CHANNEL
First Claim
1. A routing system using a NEtwork MObility (NEMO) protocol, the routing system comprising:
- a plurality of mobile routers capable of roaming in a network, the plurality of mobile routers comprising at least one top level mobile router coupled to the network via an access router; and
a central authority server configured to store information about the top level mobile routers and any mobile routers operationally attached to each of the top level mobile routers,wherein a corresponding node is configured to determine a position of a destination mobile router based on the information stored with the central authority server and to route data packets directly to the destination mobile router through a corresponding top level mobile router using the information stored with the central authority server, thereby reducing routing overheads in the network.

Abstract
Disclosed is a method for reducing routing overheads during data transmission to a destination mobile router of a plurality of mobile routers roaming in a network. The method comprises registering by top level mobile routers with a central authority server, sending data packets by a corresponding node of the network to the destination mobile router operationally attached to a corresponding top level mobile router, locating a position of the destination mobile router by identifying attachment of the destination mobile router to the corresponding top level mobile router from the information registered by the plurality of mobile routers with the central authority server, routing the data packet directly to the corresponding top level mobile router to which the destination mobile router is operationally attached and receiving the data packet by the destination mobile router from the corresponding top level mobile router, thereby reducing routing overheads in the network.
